T0 @ZZ 'tu/7,0711, it may 0072/0071721:

Be it known that I, ALBERT POWERS, a cirizen ofthe United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Stillsof which the following is a full, clear',and exact description, reference being had tothe accompanying drawings,forming a part hereof.

My invention has relation to improvements in domestic stills; and itconsists in the novel arrangement and combination of parts more fullyset forth in the specification and pointed out in the claim. g

In the drawings, Figure l is a front elevation of the still, showing theparts in their assembled position. Fig. 2 is a middle vertical sectionon line 2 2 of Fig. 1. Fig. 3 is a top plan of the lower section orboiler, and Fig. 4 is a top plan of the -upper section.

The object of my invention is to construct.

a simple still adapted particularly for domestic, campiu g, and similarpurposes, one which shall be cheap, durable, readily assembled or takenapart, and one possessing further and other advantages better apparentfrom a detailed description thereof, which is as follows:

Referring to the drawings, 1 represents the bottom section or boiler,the same being proT vided with a conical roof 2, having a centralopening 3 for the escape of the stea1n, the lower edge of the roof beingdisposed in a plane a suitable distance below the upper edge of theboiler. ripheral wall of the boiler which is above the lower edge of theroof are formed a series of air vents or openings 4, adapted to registerwith a corresponding series of openings 4' of the upper section 5 of thestill, the openings 4 being distributed in a plane adjacent to the upperedge of the boiler or section 1. Formed with the section 5 is a lowerconical wall 6, having an opening 7, and an upper conical wall 8, havinga conical perforated apex 8', the top of the apex being substantially ona level. with the upper edge of the section 5. Between the walls 6 and 8is a condensingchamber 9, from the lowest point of which extends adelivery nozzle or tube 10, to which may be attached a suitable hose.(Not shown.) Froma point in the peripheral wall of the section 5 asuitable distance belowr the upper edge Along that portion of thepethereof leads an overfiow pipe or spout 1], the lower end of the samedischarging into a pocket 12, communicating through an opening 13directly with the boiler. The compartment 14 above thewall 8, from whichthe pipe' 1l leads, is the cold-water compartment, the said waterserving to condense the vapor disengaged from' the yboiler and impingingagainst the lower surface of the wall 8. The registeringopenings 4 4 byreason of the aircurrents induced to How therethrough by the ascendingcurrents of vapor from the boiler serve to admit an amount of cool airwhich in a measure has a tendency to partially condense the vapor inaddition tothe complete condensation affected by the cool water in thecompartment 14. The latter is filled through a funnel 15, mounted in acasing or tube 16, soldered to the inner wall of said compartment.

The operation of the still is as follows: The boiler is placed over aflame or stove, and the water therein as it becomes heated evaporates,the vapor rising and condensingin the chamber 9, the distilled waterbeing discharged through the nozzle or pipe 10, from which it may beconducted to any suitable point of consumption. The bounding conicalwalls of the condensingchamber being substanstantially parallel, thevapor rising from the boiler first impinges against the lower wall,being thereby in a measure condensed before impinging againstA the upperwall of said chamber or that directly in contact with the' cold water inthe compartment 14. In this Way the direct impingement of the vaporagainst the upper wall of the condensingchamber is prevented and thetoo-rapid heating of the-water in the compartment 14 is avoided. As thewater in the cold-water compartment 14 becomes heated more cold watermay be supplied thereto, the overflow passi ing through the spout 11back to the boiler again. The perforation in the apex 8' is to relievethe stillfof any excess of pressure due to a too-rapid generation ofsteam. By having the bounding walls of the chamber 9 con ical orinclined the distilled or condensed water may readily flow to thedischarge-nozzle 10.

During the operation of the still a small IOS quantity of condensedwater will naturally collect around the lower edge of the roof 2 andeventually rise tothe openings 4. U11- der ordinary circumstances theair-currents passing through said openings will carry off mechanicallyany condensed water which might tend to flow out through said openings,and should the condensation beoolne too rapid the openings may be closedcompletely by giving the sections a slight turn about their common axisand destroying the register between the openings 4 and et.

It is of course apparent that minor changes may be resorted to withoutdeparting from the spirit of my invention.

Having described my invention, what I claim is- A still comprising alower section or boiler, a conical roof for the same having a centralopening, the lower edge of the roof being disposed in a plane below theupper edge of the boiler, an upper section adapted to be coupled to theupper edge of the boiler, the two sections having openings or air-ventsadapted to register with one another, ata pointabove the base of theroof of the lower section, a condensing chamber in the upper sectionbounded bya lower and an upper conical wall substantially parallelthereto and separated by a suitable space therefrom, the upper wallhaving a perforated apex, and the lower wall having a central openinglocated above the corresponding opening of the conical roof of the lowersection, a cold-Water compartment formed in the upper section above theupper wall of the condensing-chamber, a pocket located on the outside ofthe boiler and communicating with the interior thereof, an overflow pipeor spout leading from the cold-Water compartment and discharging intosaid pocket, and a discharge-nozzle leading from the condensing-chamber,the parts operating substantially as, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT POWERS.
